  • each tab terminal T 1 is connected to a male terminal (not shown), received in a connector 17 , 18 , through a relay terminal 16 of a female-female type.
  • the wires 5 are so-called sheathed (or covered) wires, and are arranged on the bus bar board 1 at predetermined intervals, and extend in a direction perpendicular to the direction of extending of the junction bars 3 a, 3 b, 3 c, 3 d and 3 e.

Therefore, by suitably determining the amount of resilient deformation of the resilient contact piece portion and an elastic coefficient thereof, the good electrical connection can be obtained regardless of dimensional tolerances, developing between each of the juxtaposed bus bars, mounted on the insulative bus bar board, and the terminal holding openings. Therefore, the dimensional tolerances of the component parts can be made less strict, and therefore the production cost is reduced, so that the productivity can be enhanced.
